Yl105 Datasheet 〈DELUXE — 2025〉

| Pin Number | Pin Name | Description | | :--- | :--- | :--- | | | GND | Ground (Power Supply Negative) | | 2 | VCC | Power Supply (1.9V – 3.6V) | | 3 | CSN | SPI Chip Select (Active Low) | | 4 | SCK | SPI Clock Input | | 5 | MOSI | SPI Data Input (Master Out Slave In) | | 6 | MISO | SPI Data Output (Master In Slave Out) | | 7 | GIO1 | General Purpose I/O / Interrupt Pin 1 | | 8 | GIO2 | General Purpose I/O / Interrupt Pin 2 |

Below is a basic code structure for interpreting the data: yl105 datasheet

Any neodymium (rare earth) magnet works best. Small 5mm diameter, 2mm thick N35 magnets provide reliable switching up to 10mm. | Pin Number | Pin Name | Description

| Sensor | Type | Key Difference | |--------|------|----------------| | A3144 | Unipolar Hall | Very common, similar to YL105’s IC | | SS495A | Linear Hall | Analog output, measures field strength | | US5881 | Unipolar Hall | Lower power consumption | | KY-024 | Module with analog output | Includes both DO and AO | | TLE4905 | Unipolar Hall | Higher temperature range | Always verify with the silkscreen on your specific board

(Note: Pin numbering may vary slightly depending on the specific PCB revision, but GND/VCC are usually on the ends. Always verify with the silkscreen on your specific board.)
